Specification forming part of Letters Patent No. 40,220. dated October 6, 1863.

To all whom it may concern Be it known that I. RIcHARn YEILDING, of

.'Ypsilanti, in the couuty'of Washtenaw and State of Michigan, have invented a certain new and useful Improvement in Antifriction Journal-Bearings; and I do hereby declare the following to be a full and exact description of the same, reference being bad to the accompanying drawings, making part of this specification, in which- Figurel is a front elevation illustrating my journal-bcarin g applied to carriage-axles. Fig. 2 is a horizontal sectionof the same at a: as, Fig. 1. Fig. 3 is a transverse section thereof at y 3 Figs. 1 and 2. Fig. etis a transverse section thereof at z 2, Figs. 1 and 2.

Similar .letters of reference indicate correspondi-ng parts in the several =figures.

My invention relates to that class of bearings in which the journals work upon the peripheries of wheels or rollers in such a mannor as to reduce the friction.

The present improvements consist, first, in the use of boxes of novel construction to contain the friction-wheels, exclude dust, and afford means of attaching the bearings in any position and upon any part of the main axle of a carriage or upon any portion of amachine to which the invention may be applied; second, in the use of oil-reservoirs peculiarly constructed and applied to avoid waste of oil and afi'ord constant lubrication to the journals of the antifriction-wheels.

In order that others skilled in the art to which my invention appertains may be enabled to fully understand and use the same, I will proceed to describe its constructionand operation.

a a may represent journals formed upon an axle, A. to which a wheel may be attached,

. stitute oil-tightchambers FF, for containing oil by which the pivots or journals of the rollers B B are lubricated constantly and with out waste.

To prevent the escape of oil the pivots of the wheels B B are made to tightly fit and close the apertures in thefannular disks 0, in which they run, and the ends of the said rollers are formed with collars immediately around their pivots, which work in contact insertion of the axle A, and may be mounted upon a hollow beam, H, which may be passed over the end of the main axle of a carriage in position to place the auxiliary axle A above,

beneath, in front, orin rear of the main axle,

as preferred.-

h h represent lugs, to which the shaftscor tongue of the carriage may be attached'in customary manner.

The above description illustrates one mode of applying my invention to buggies or other carriages. I do not, however, desire to be understood as limiting myself thereto, nor to any specific manner of applying the invention. It may be applied to all descriptions of wheel-vehicles and the shafts of stationary machinery of various kinds.

I prefer to use four of the antifrictionwheels to each journal, but may usea less or greaternumber, as circumstances or preference dictate. The wheels mounted and arranged as above described afi'ord cleanly bearings, avoiding wear and friction to the greatest possible extent, and the use of. the oil-tight reservoirs F insures a constant lubrication of all parts exposed to friction, without waste of the lubricating material. I. propose to use for lubricating purposes such oil, grease, or com-' pound as may have the necessary properties and consistency according to the temperature, the speed of motion, and other circumstances It will be evident that by the manner de' scribed of fitting the pivots -in apertures ex.

tending through the annular disks 0 C so that their ends will work in contact with the lubricating material I am enabled to use a material or compound which may assume a solid form when not in use, and, being melted by the warmth of the pivots, will work into their bearings with suflicient freedom to prevent inju rious heating.

I may represent the main axle of the carriage, J. one of the wheels, and K a portion of the shafts. a may represent the nut for confining the wheel on the auxiliary axle, and a the nut for securing the auxiliary axle within the boxes D D. 7

Having thus described my invention, what pivots.
